What is grape pie?

Grape pie is a deliciously tart and sweet pie that can be made year round, but is especially delicious when California grapes are in season in late summer and into fall. It’s similar in texture to other fruit pies, but with a classic grape flavor!

Where did grape pie originate?

Grape pie was first made in the 1950s in New York as a double crust pie. It has steadily grown in popularity over the last 80 years and people enjoy it nationwide during the holiday season and beyond.

How to make a grape pie more blood sugar friendly

Traditional grape pie recipes will end up have >60g carbohydrate per slice and not a whole lot of fiber and protein. Our recipe below has about half the amount of carbohydrate and a decent amount of protein and fiber. 

We utilized the following strategies to make this grape pie more blood sugar friendly:

  • Almond flour and oat crust
  • Less added sugar
  • Crumb topping instead of top crust 

What’s in this California grape pie recipe?

I’m so excited for you to try this grape pie recipe. It’s got some of the classic features you see in many of my recipes.

Almond flour and oat crust

 This crust recipe is based on a recipe in my second cookbook The Easy Diabetes Desserts Cookbook. By using a flour base of almond flour and oats, we reduce the overall carbohydrate count and increase protein and fiber.

California grape filling

Our delicious grape filling is made with California grapes! I chose black seedless grapes for the photos you see here, but you can use any form of grapes you like. The instructions are written as if you’re using seedless, but seeded will work also once the seeds have been removed. 

California grapes are a versatile signature ingredient in both simple and upscale recipes … And, grapes may help support a healthy immune system. Studies have shown that adding heart-healthy grapes to your diet every day also helps support brain, colon, and skin health; maintaining healthy bodily systems is essential to defend against illness both this time of year and year round.

Oat crumb topping

Instead of doing a double crust pie that has a crust on the bottom and on the top, we switch out the top crust for a delicious oat crumb topping. This adds a fun crunchy texture, reduces the overall carbohydrate count, and increases the fiber content slightly.

California Grape Pie filling tips 

For our filling, we’re going to use the same strategy that we do in my Homemade Uncrustables recipe and my Grape Jelly BBQ Meatballs recipe. We’re essentially heating our grapes on the stove until they start to release their juices and then reducing that down until we get a thick almost-jam-like consistency. 

Make sure to keep a close eye on your pot during this step, if the grapes aren’t stirred often enough and/or your stove gets too hot, the grapes can burn.

California Grape pie recipe with crumb topping

To make our crumb topping, we’re using the same base as we do for our crust: almond flour and oats. We’re adding some butter and a small amount of brown sugar for the perfect grape pie topping. 

How to make a crumb topping

Oat crumb topping is not only delicious but it’s pretty simple to make! We start with mixing softened butter, almond flour, oats, and spices by hand. Using your fingers to smoosh the pieces of better helps it to soften even more and after a couple minutes we end up with something that resembles wet sand. Then, we sprinkle this on top of our prepped pie crust and filling and it’s ready to be baked.

  • Remove the mixture from the stove top and stir in the ground up oats.
  • While working on the filling (which will take ~40-45minutes), we will make our crust and oat crumb topping.
  • Gather your crust ingredients (almond flour, oats, sugar, melted butter, egg, salt and vanilla extract) and add them to the bowl of a food processor or your blender. Process them all together until the mixture resembles wet sand (about 15-20 seconds). Then, carefully transfer the mixture to a greased 8 or 9 inch pie plate and press it down and up the sides. Place the pie plate in the oven and bake for 10 minutes. Once done, set it aside to add your filling to.
  • Add all of the crumb ingredients (brown sugar, cinnamon, oats, almond flour, butter, and salt) to a bowl. Using your hands, mix the topping together, squishing the butter into the mixture as you go. It should start to resemble wet sand.
